Title: Method for finishing outside plating weld zone of ship
Inventor: SAIGA YOSHINORI
IPC: B23K9/013
Filed: 1983-01-19
Abstract: PURPOSE:To finish flatly the outside plating weld zone of a ship in a short time with less labor by melting the reinforcement of weld on the outside bead in the outside plating weld zone of the ship by an arc, etc. thereby smoothing the same. CONSTITUTION:A weld bead 2 in the outside plating weld zone of a ship forms a reinforcement of weld having a thickness H from outside plates 1 which are base materials. Since the reinforcement of weld increases friction to sea water during navigation, it is required to be flattened. A TIG welding machine is used in this case and an arc 5 is generated between the electrode 4 of the welding machine and the bead 2 with said machine. The reinforcement of weld is melted by said arc and the bead 2 is flattened.

Abstract: PURPOSE:To remove a protective film material on a face except the end face to be radiated with a light without depending upon a manual work by reactive ion etching the three faces of a semiconductor light emitting element with reaction gas containing no oxygen, and removing the material on the face except the end face to be radiated with the light. CONSTITUTION:When a protective film material on a face except the end face to be radiated with a light of a semiconductor light emitting element is removed, the three faces of the element are reactive ion etched with reaction gas containing no oxygen (O2), thereby removing the material on the face except the end face. That is, by using a device for etching the protective film by reactive ion etching (RIE), and SiN films are adhered in advance to the three faces of a substrate. When the reaction gas of CF4+O2 is used, SiN on the three faces are all etched, but when CHF3+H2 is used, only the SiN remain on both sides. Thus, the material adhered to the part except the light emitting end face of a semiconductor light emitting device can be removed without depending upon a manual work.

Abstract: PURPOSE:To enable an operator to control a cursor with his hands on the keyboard side, by providing a cursor control means which controls the position of the cursor displayed on a display device on a basis of outputs of manipulated variable detecting means. CONSTITUTION:A cursor 2 appearing on the screen of a CRT display device 1 is controlled by the operation of either of track balls 5a and 5b on two separated keyboard bodies 3a and 3b. For example, when the track ball 5a on the separated keyboard body 3a is moved with the thumb of the right hand, a manipulated variable detecting means 6a detects the manipulated variable of the track ball 5a to control a cursor control means 7, and therefore, the cursor 2 is moved in accordance with the manipulated variable of the track ball 5a. If only the thumb is moved from the track ball 5a to a button 9a to depress the button 9a when the cursor 2 reaches a prescribed position, the next program which this position means is driven. Thus, the operation is made easy to reduce the erroneous operation and the operation time is shortened.
